Device for checking for incomplete locking of connector housings

摘要

An automatic lock checking device for a wire harness connector having short-circuiting female and male terminals for checking for incomplete locking thereof, including a diagnostic resistance-containing circuit connected parallel with a circuit containing a sensor and having the positive and negative sides thereof connected through conducting terminals of the connector to a load or an electronic control unit adapted to process input signals from the sensor. The automatic lock checking device includes at least a pair of short-circuiting terminals connected in series in the diagnostic resistance circuit and arranged to be short-circuited when the connector is completely locked.
